If Google PageSpeed Insights shows “Ensure text remains visible during webfont load,” your browser is waiting too long to display text while a web font is loading.
Visitors may see a blank area where text should be, especially on slower connections.
The fix is usually straightforward: make the browser display a fallback font while the custom font loads, reduce unnecessary font files, and make important fonts available sooner.
For most WordPress websites, the biggest improvements come from using font-display: swap, reducing font weights, serving modern font formats, and avoiding unnecessary font requests.
What Does “Ensure Text Remains Visible During Webfont Load” Mean?
When a website uses a custom font, the browser has to download the font before it can use it.
If the font-loading behavior prevents text from being displayed, visitors may temporarily see invisible text.
This is commonly called FOIT — Flash of Invisible Text.
The browser has the content, but the text isn’t visible because the required web font hasn’t finished loading.
Google PageSpeed Insights can flag this situation because visible text gives users something to read while the font is downloading.
The CSS font-display property controls how the browser handles this process. MDN documents five values: auto, block, swap, fallback, and optional.
Why Does This Warning Matter?
The problem isn’t simply that a font takes time to download.
The bigger issue is that the browser may delay showing useful content while waiting for that font.
This can affect:
- Perceived loading speed
- First Contentful Paint
- Largest Contentful Paint
- Layout stability
- User experience
Fonts can also contribute to layout shifts when the fallback font and final font have significantly different dimensions.
That’s why font optimization needs to balance visibility, loading speed, and visual stability.
The Most Important Fix: Use font-display: swap
For many WordPress websites, font-display: swap is the simplest starting point.
Example:
@font-face {
font-family: ‘MyFont’;
src: url(‘/fonts/myfont.woff2’) format(‘woff2’);
font-display: swap;
}
With swap, the browser can display the fallback font while the custom font loads.
Once the custom font is ready, the browser swaps it in.
This prevents the page from keeping text invisible while the font downloads.
MDN also recommends font-display: swap as a practical web-font performance technique because the browser can render using the fallback system font instead of blocking text rendering.
What Is the Difference Between FOIT and FOUT?
There are two common font-loading behaviors.
FOIT: Flash of Invisible Text
The text isn’t visible while the browser waits for the custom font.
This creates a blank text area.
FOUT: Flash of Unstyled Text
The browser displays fallback text first and then replaces it with the custom font.
The text remains visible, but its appearance changes when the custom font arrives.
For most websites, visible text is preferable to invisible text.
That is why font-display: swap is commonly used.
1. Check Your WordPress Font CSS
First, find where your fonts are being loaded.
Your fonts may come from:
- Google Fonts
- Elementor
- Your WordPress theme
- A page builder
- A performance plugin
- Custom CSS
- A font-management plugin
- Your own server
Open your page source or Chrome DevTools and look for .woff2, .woff, .ttf, or .otf files.
Then inspect the corresponding @font-face rules.
You may find something similar to:
@font-face {
font-family: ‘Example Font’;
src: url(‘/fonts/example.woff2’) format(‘woff2’);
}
If font-display is missing, add an appropriate value such as:
font-display: swap;
2. Use WOFF2 Fonts
If you’re still serving old font formats, consider switching to WOFF2.
WOFF2 provides better compression than older formats and is widely supported by modern browsers.
A smaller font file means less data needs to be downloaded.
For modern websites, WOFF2 should generally be the first format to consider.
MDN’s web performance guidance recommends WOFF and WOFF2 for web fonts and notes that they provide built-in compression advantages compared with formats such as EOT and TTF.
3. Reduce the Number of Font Weights
One of the easiest font optimizations is simply using fewer fonts.
For example, your website might load:
- Regular 400
- Medium 500
- Semi-bold 600
- Bold 700
- Extra-bold 800
If your design only needs 400 and 700, loading all five creates unnecessary requests and additional data.
Review the font weights actually used on your website.
Remove the ones you don’t need.
This is particularly useful on WordPress websites using page builders because themes and plugins can sometimes load more font variants than the design actually requires.
4. Reduce the Number of Font Families
Using three or four font families can quickly increase the number of font files.
For example:
Heading: Font A
Body: Font B
Buttons: Font C
Icons: Font D
Every additional family can add more resources.
If your design works with one or two families, keep it simple.
A smaller font setup is usually easier to optimize and maintain.
5. Host Fonts Locally When Appropriate
If your website loads fonts from an external provider, the browser may need to establish another connection before downloading the font.
Self-hosting can give you more control over:
- File format
- Cache headers
- Font files
- Preloading
- Privacy
- Delivery
This doesn’t mean every external font must be self-hosted.
The correct choice depends on your setup.
But if fonts are creating unnecessary connection overhead or you’re already optimizing your site’s assets, local hosting is worth considering.
6. Optimize Google Fonts
Google Fonts are common on WordPress websites.
A page can accidentally load several families and weights from Google Fonts without the website owner realizing how many font files are involved.
Review your theme and page builder settings.
Remove fonts you don’t actually use.
If you only need:
Roboto 400
Roboto 700
don’t load:
Roboto 100
Roboto 300
Roboto 400
Roboto 500
Roboto 700
Roboto 900
Every unnecessary variant increases the amount of work the browser has to perform.
7. Preload Only Critical Fonts
Preloading tells the browser to request an important resource earlier.
For example:
<link
rel=”preload”
href=”/fonts/myfont.woff2″
as=”font”
type=”font/woff2″
crossorigin
>
This can be useful when a specific font is needed immediately for important above-the-fold text.
But don’t preload every font on the website.
If you preload too many resources, they compete for bandwidth with other critical resources.
Only preload fonts that are genuinely important to the initial page rendering.
8. Make Sure the Preload Matches the Actual Font
A common mistake is preloading a font that the page doesn’t actually use.
Another is forgetting the correct crossorigin attribute when required.
The browser should be able to match the preload request with the later font request.
If it can’t, the preload may provide little or no benefit.
After adding a preload, check Chrome DevTools → Network and confirm that the font is requested as expected.
9. Use a Good Fallback Font
The fallback font matters.
Consider:
body {
font-family: ‘MyFont’, Arial, sans-serif;
}
If MyFont hasn’t loaded yet, the browser can use Arial or another available fallback.
Try to choose a fallback that has similar characteristics to the final font.
A very different fallback can cause noticeable changes in:
- Text width
- Line breaks
- Heading height
- Button size
- Layout
That can create visual movement when the custom font eventually loads.
10. Reduce Font File Size With Subsetting
Font files can contain thousands of characters.
If your website only uses the Latin alphabet, you may not need every glyph contained in a complete font family.
Font subsetting removes unused characters from the font file.
For example, a website serving only English content may not need glyphs for dozens of writing systems.
A smaller subset means a smaller download.
This can be particularly useful for websites using large font families.
11. Avoid Loading Icon Fonts When SVGs Will Work
Icon fonts were once extremely common.
Today, SVG icons are often a better choice for performance and flexibility.
Instead of loading an entire icon font just to display a handful of icons, you can use optimized SVG assets.
This can eliminate an unnecessary font request and reduce the amount of data the browser needs to download.
MDN also recommends considering compressed SVGs instead of icon web fonts where practical.
12. Don’t Load Fonts You Don’t Use
This sounds obvious, but it happens frequently.
A WordPress theme may load a font globally even though only one page needs it.
A page builder may load font styles that aren’t being used.
A plugin may add another font family.
Use Chrome DevTools to identify every font requested by the page.
Then ask:
Does this page actually need this font?
If the answer is no, remove the request.
13. Be Careful With Font Optimization Plugins
Performance plugins can modify font loading automatically.
Depending on the plugin, optimization may include:
- Font preloading
- Local font hosting
- Font compression
- CSS modification
- Font-display changes
- Google Font optimization
These features can be useful, but don’t enable several different plugins to perform the same optimization.
Multiple optimization layers can create duplicate requests or unexpected behavior.
If you’re already using a WordPress caching and optimization plugin, check its font settings before adding another font plugin.
For example, if you’re using Swift Performance, its configuration should be considered alongside the rest of your asset optimization rather than adding another layer blindly. You can see our guide to configuring Swift Performance.
14. Check Elementor and Theme Font Settings
Elementor and other page builders can add their own font loading behavior.
Your theme can also load fonts independently.
This means changing one font setting may not remove all font requests.
Check:
- Theme typography settings
- Elementor global fonts
- Custom CSS
- Google Fonts settings
- Plugin-generated CSS
- Header templates
- Page-specific styles
Remove duplicate font sources wherever possible.
15. Don’t Preload Every Font
Preloading is powerful, but overusing it can hurt performance.
Suppose a website uses six font files.
Preloading all six tells the browser to request all of them early.
Those requests can compete with:
- LCP images
- CSS
- JavaScript
- HTML
- Other critical resources
The goal is not to make every font load early.
The goal is to make critical content appear quickly.
16. Use font-display: optional When Appropriate
font-display: optional is another strategy worth considering.
With optional, the browser has more freedom to decide whether to use the web font based on loading conditions.
This can be useful when the custom font isn’t essential to the page’s first render.
However, it can also mean some users may continue seeing the fallback font instead of the custom font.
So don’t automatically replace swap with optional.
Choose the behavior based on the importance of the font to your design.
17. Check Font Loading With Chrome DevTools
You don’t need to guess what’s happening.
Open Chrome:
Right click → Inspect → Network → Font
Reload the page.
You can see:
- Which fonts load
- Their file sizes
- Request timing
- Whether they are loaded locally
- Whether they are loaded from a third party
You can also inspect the CSS rules that control each font.
This makes it easier to identify unnecessary font requests.
18. Test With PageSpeed Insights
After changing font settings, run the page through Google PageSpeed Insights.
Check whether the warning has disappeared.
But don’t stop there.
Also review:
- LCP
- CLS
- FCP
- Network requests
- Font loading time
- Visual appearance
A warning disappearing isn’t enough if your page becomes visually unstable.
Google’s current Core Web Vitals documentation is a useful reference when evaluating broader page performance. Google’s Core Web Vitals documentation
19. Check for Layout Shifts After Changing Fonts
Changing font loading behavior can affect CLS.
For example, your fallback font may be much wider than the final font.
When the custom font appears, text can reflow.
To reduce this problem, choose a fallback font with similar metrics.
Modern CSS also provides tools such as:
- size-adjust
- ascent-override
- descent-override
- line-gap-override
These can help make fallback fonts closer to the final font.
The result is less visual movement when the custom font becomes available.
A Practical WordPress Font Optimization Setup
For most WordPress websites, start with this approach:
Step 1: Keep only the fonts you need
Remove unnecessary families and weights.
Step 2: Use WOFF2
Convert or replace older font formats where appropriate.
Step 3: Add font-display: swap
Make sure important text remains visible while fonts load.
Step 4: Optimize font files
Subset fonts and remove unnecessary glyphs when possible.
Step 5: Preload only critical fonts
Preload the font required for important above-the-fold content.
Step 6: Check fallback fonts
Choose a fallback with similar dimensions.
Step 7: Test mobile
A font that loads quickly on a desktop connection may behave differently on a slower mobile network.
Step 8: Test the actual website
Check menus, headings, buttons, forms, and layouts after optimization.
Example of a Basic Optimized Font Setup
@font-face {
font-family: ‘WebsiteFont’;
src: url(‘/fonts/website-font.woff2’) format(‘woff2’);
font-weight: 400;
font-style: normal;
font-display: swap;
}
body {
font-family: ‘WebsiteFont’, Arial, sans-serif;
}
Then, if the font is genuinely critical, preload it:
<link
rel=”preload”
href=”/fonts/website-font.woff2″
as=”font”
type=”font/woff2″
crossorigin
>
Don’t copy this code blindly.
The font URL, weight, style, and loading strategy must match your actual website.
Common Mistakes to Avoid
Loading too many fonts
More font files mean more requests and more data.
Preloading everything
Too many preloads can compete with more important resources.
Using large TTF files
Use modern web formats where possible.
Ignoring fallback fonts
A poor fallback can cause layout changes when the custom font loads.
Keeping unused font weights
Remove weights your design doesn’t use.
Using several font optimization plugins
Avoid overlapping optimization systems.
Testing only desktop
Always check mobile performance too.
Frequently Asked Questions
How do I fix “Ensure text remains visible during webfont load” in WordPress?
Use font-display: swap, reduce font files and weights, serve WOFF2 fonts, remove unused fonts, and preload only critical fonts when necessary.
What does font-display: swap do?
It allows the browser to display fallback text while the custom web font downloads, then replaces the fallback with the custom font when it becomes available.
Should I preload all WordPress fonts?
No. Preload only fonts that are critical to the initial page render. Preloading too many fonts can compete with other important resources.
Is WOFF2 better than TTF for websites?
Yes. WOFF2 is designed for web delivery and generally provides much better compression than older font formats such as TTF.
Can web fonts affect Core Web Vitals?
Yes. Font loading can affect rendering and layout stability, which can influence metrics such as LCP and CLS.
Final Thoughts
The “Ensure text remains visible during webfont load” warning usually means your fonts are being loaded in a way that delays visible text.
The most effective solution is not to load more fonts faster.
It is to load fewer fonts, make text visible immediately, and prioritize only the fonts that matter.
Start with font-display: swap, remove unnecessary font weights, use WOFF2, optimize font files, and preload only genuinely critical fonts.
Then test the result on both desktop and mobile.
A good font setup should make your website look the same while allowing visitors to see useful text without waiting for a custom font to finish downloading.
